Does anyone know why, CopyBuffer can't catch the data? (CopyBuffer returns -1, I use GetLastError to check the error code is 4806)

int OnInit()
{
Handle_ATR=iATR(_Symbol,PERIOD_D1, 1);
}
int OnCalculate(......)
{
  CopyBuffer(Handle_ATR,0,0, 1, atr);
}

Example: getting iATR data from a custom indicator.
